Introduction of Research
Organic molecules can exhibit different properties even when they have the same molecular structure, depending on how they are arranged in the crystalline state. This phenomenon is known as crystal polymorphism and can have a significant impact on various functions, including luminescence, electronic properties, and responses to external stimuli.
Our research focuses on crystal polymorphism, with particular attention not only to how molecules are arranged in crystals, but also to how the molecular structure itself changes depending on the crystal environment. By understanding the mechanisms of functional expression from both molecular arrangement and molecular structure, we aim to control the functions of organic molecules in the crystalline state.
By combining molecular design and synthesis, crystal structure analysis, and property evaluation, we seek to clarify the relationships between structural changes and functional changes induced by crystal polymorphism, ultimately leading to the creation of new functional organic materials.
